I played a little online poker several years ago, at PokerStars.net, before everything blew up and cash games were outlawed. It was fun, but also frustrating, when someone at the table would just "all-in" everyone else to death. It's a strategy that would never fly at a real table.
These days I keep to my Wii, but I find myself playing older N64 games that I've downloaded more than anything new. Love that Mario!
